摘要: 鋼鐵企業面臨庫存增加、產能過剩、盈利艱難等問題，迫切需要通過綠色化和智能化的發展來應對當前的嚴峻形勢.基于鋼鐵企業制造流程特點，通過分析企業以鐵素流為核心的物質流和相應能量流網絡特征，針對企業現有信息化系統在物質流和能量流協同方面存在的問題，提出鋼鐵制造過程的物質流和能量流的協同方法，明確物質流和能量流的耦合應從鋼鐵制造的單元工位設備與整體流程網絡兩個層面進行規劃、設計和實施，并且指出可從完善信息監控、進行計劃協同和調度協同三個方面來實現協同優化.構想基于現有信息系統架構，通過增加相應企業資源計劃系統、制造執行系統、能源管理系統等信息系統的功能，以及建立物質流和能量流協同優化信息子系統的方式，以鋼鐵制造過程的物質流和能量流相關信息的數字化及模型化為支撐，實現制造流程的物質流和能量流協同優化，達成生產優化、資源優化和能源優化的效果.Abstract: Iron and steel enterprises are facing difficult problems such as increasing inventory, excess capacity, and poor profitability. It is urgent to solve them through the development of green and intelligent manufacturing technology for iron and steel enterprises to address the current critical situation. Based on the analysis of the characteristics of manufacturing processes in iron and steel enterprises, the materials flow (with a core of iron element flow) and its corresponding energy flow network, as well as the deficiencies of the synergy between materials flow and energy flow in existing enterprise information systems, synergetic optimization methods between materials flow and energy flow in the iron and steel manufacturing process were investigated in this paper. It revealed that the coupling between materials flow and energy flow should be planned, designed and implemented for both the unit manufacturing equipment and the overall manufacturing process. The synergetic optimization can be achieved by three approaches, including perfecting information monitoring, synergizing planning and synergizing scheduling. Based on the analysis, a schematic resolution on top of the existing information system architecture was proposed towards the optimization of production, resource and energy. The synergetic optimization between materials flow and energy flow in the iron and steel manufacturing process can be realized by improving the corresponding functions of the existing manufacturing execution system, enterprise resource planning and energy management system, facilitated by a newly proposed information subsystem handling the synergetic optimization with the support of digitization and modelling of the relevant information in materials flow and energy flow.
